Application filed December To u ll its/mm. it "may concern} s lie it'ln'wwn'thut Lotus l. llsnsinu icling in Fulladelphia,rl ennsylrlu have invented cer-. lulu improvements in Menus for Filling lloleswith Concrete; oi, which theit'ollowin is ai -specification. I

M y. invention relutes particularly to menus for formingconcrete piles especially ot'the type inwlnch u shell of concrete is lirst inserted in'lhe grounthn hiclr is afterward tilled witha concrete mixture, and whcnthis concrete is sct the pile is at hoinogenons inns My invention'cairbe used for filling any deep. hole with concrete no matter by What process the hole is made, or whether it is lined. or not, and also may be used in discharging a concreteinixture'nntler water.

T he object ofiny invention is to place the concrete in the hole in such a manner that the stone, sand, and cement will not separate, thus insuring the proper 'cc nentation of the mixture. i

It is well known that if concrete is dropped from any height the particles of cement, sand and stone separate so that the mixture is destroyed and the bond weakened. The method now in use for filling deep holes is to use a trip liuclzetin which the concrete is placed incl the bucket lowered in the hole and so tlisclmrgedthat there willbe Very little full to the niixture, but this is tedious and uncertain, whereas by ny invention the concrete can be measured so as to insure the proper amount oi? concrete being inserted in the hole .iind separation of the ingredients is rendered impossible; furthermore the apparatus 'a'cts ass gage, insuring the hole being of u-"proper tliumeter throughout.

View of a inedilicution illustrating a sectional apparatus in which the doors dispensed with; and Fig. .11, is s View showing at detachable door. A is a tube made in any length desired either in a. single piece or in sections, as shown in Fig. l; the sections being; ointed together at a in any suitable manner. in the present instance I have shown a sleeve on one section and pins on the other adapted. to slots in the sleeve, forming u l'ia yonet joint connection, and one section is turnctl with respect to the other nhen it is dcsirctl to couple or uncouple theseetions.

At the upper of: the tube A is a. funnel A and attached to the tube are the hoist.- ing chains 6. 5 connected to suitable inecl'ianisni for raising or lowering the tube. As shown in Figs. 1., doors 0 are arranged at inteiw'z ls throughout the length of the tube uncithose doors in the present instance are pointed. at 0", one being provided with :1- latch a so that they can be locked. when closed. Each door is pref-- eruhly arranged that its inner surface will tube so that no obstructionsere formed to interfere with the discharge of the material. In some instai'ices, however the door may he of a sliding type, as illustrated at 0 Fig. *5 instead of a pivoted door. made detach able as in Fig. 11, or arranged in any other manner found desirable.

At the bottom of the apparatus is s pivoted door D hinged to the body portion at d in the present instance and heid'closed. by e. hitch cl of any suitable construction. A rope a is attacheii to the latch uncl extends alongside the tube, as shown indottet lines he on a line with the inner surface of the "ill piece D to allow the contents of the tube to .tube through the section D o upgs 1n the arms f,

' proved form of pile, for which I when it is opened and the concrete 'inixture Fig, 4, from any'convenient point so that it Y A is inserted through the doorway untll the can be operated from the surface of the ground when it is desired to trip the door concretereaches the point indicated in and allow the contents of the tube to be dis- 4, when the door is closed and the apparatus charged. owered The seconddoor is then opened 70,

and more concrete is inserted until it reaches dge of the said doorway, when the second door is closed and the next door opened, and so on until-the tube is filled with the mass. of concrete and extends a roper tance int0,the hole, as illustrated m Fig. 5. By prcfviding a funnel at the uppet'b n d In place of the trip door a plate D of glass, pottery, or other fragile material may be mounted in the bottom of the tube A, as shown in Fig. 8, held by a flange a, and a projection may be formed in the bottom of the hole for breakingthis fragile bottom as soon as the tube is raised. In Fig. 9, I have shown a block D held at the lower end of the tube A by two pivoted arms f, f held in place by a rod I the rod extending from the upper end of the and through which are pivoted at f sothat on withdrawing the rod F the arms willbe released and the section D 7 v proximity to the bottomof the hole, then the fdoor D at the bottom of the tube can be tripped by ulling upon the cords d and the door will -y open, as illustrated in Fig. 6 discharging the concrete into the bottom of. may be used to temporarily. the hole. Then the tube is raised by'any suitable hoisting mechanism and the crete will be discharged. from thetub'e into the hole with practically no fall, and consequently the particles-will not become separated and a much stronger cgncrete pile structure will be made than wheie the material is to be intermittently discharged 'or dropped from any considerable height. One great advantage in discharging maby my improved device is that the device itself acts as a gage when insorted in the hole, insuring the hole being of the proper diameter throughout when the concrete is placed therein. Furthermore when tubular pile sections are used, as shown' in the drawings, it will detect any misalinement of these sections should one break away from another by the pressure of the earth, thus the operator is assured, when the tube is inserted to a certain depth, that the hole is improper condition to receive the con be discharged the l hole. I

In Fig. 10, I have shown a sectional tube AF; the sections A being short and coupled together by bayonet joints a As one secion is filled with concrete it is lowered into the ground and another section t'ddedto it I and filled, and so on until the tube reaches the desired depth. Ears i may be provided on each section to which may be attached the hoisting chains. The hoisting chains may be permanently attached to the lowermost section as shown and the other sections may be built upon this section, if desired.

In Figs. 4:, 5 and 6, I have shown my improved apparatus used in fillin an imhave filed for patent, Serial N 0. 364,623, 1907. This form of pile point section N and a tubular an application on March 26, consists of a casing M, which is driven 111 the ground crete to make a perfect pile. with the point section and after this casing claim 7 115 is driven in the ground it"isfilled with con- 1.

I

.The operation of the apparatus is as fol-' lows :--As illustrated in I igs 5 and 6, the l apparatus is suspended above the hole, as illustrated in Fig. at, and the door at the bottom closed and the apparatus lowered until the first door from the bottom is about on a line with the surface "of the grouiid with concrete at progrcssm l e round, and. means for opening the bottom 0% the tube so as to allow the entire mass to be discharged into the hole without disintegrating the 121$ mass. a H, 2.
